Hello, I've been lurking for a while and have a basic question.
where are the requirements/design docs? Where are the accomplishments and milestones listed. How are tasks divided.

finally regarding blind and other handicap access, is this project allowed to think out of the box a bit or are there fixed platform constraints. Namley I am thinking that a cheap hardware interface might be a superior solution. to name two:
virtually all blind people are completely comfortable with a touch tone phone key pad (and listen & speak to the hand set for that matter ("press or say "one" to choose to vote no"). Standardizing on this would allow for the minimum capabilites to be set at a very high standard right form the start.
The interface would add virtually no costs since it could use a real phone connected to a modem port or sound card on the computer.

as a second example, a common interface on wheel chairs for the muscularly week is a joy stick or wheel. again this allows for a somewhat high level navigation tool.

I dont know much about blow tubes but in my ignorance I would assume that they have some operation mode that is not strictly binary (e.g. blow pattern based).

by the way, to keep things inexpensive and robust I'll note that a telephone based input can be adapted to both blow tubes (by sound) and to joy sticks/wheels (that glove over the buttons--they make childrens toys like this for keyboards)

why set the minimum standard to a binary input schema if it can be avoided?

I have now implemented this, and I realize that the arrow keys aren't
enough. One must be able to erase a letter - this can be done with the
up arrow. But I also think that one should be able to get instructions
at this point. Can we add the space bar as a general help key? It should
be quite easy to find on the keyboard. Then hitting the space bar will
provide relevant help at all stages (will not work when a voter types in
a write-in candidate using the keyboard).
